Re: [platform-swt-dev] Expandable Group Widget

[Carolyn MacLeod <Carolyn_MacLeod@xxxxxxxxxx>]

Hello again, Benoit.
If you need to emulate this behavior
before the 'expandable group' widget exists, here is a snippet that shows
how to do it using a FormLayout.
Carolyn

import
org.eclipse.swt.*;
import
org.eclipse.swt.events.*;
import
org.eclipse.swt.layout.*;
import
org.eclipse.swt.widgets.*;

public
class
DetailsButtonTest {
        static
Display display;
        static
Shell shell;

        public
static
void
main(String[] args) {
         
      display
= new
Display();
         
      shell
= new
Shell(display);
         
      shell.setLayout
(new
FormLayout());

         
      Button button = new
Button(shell,
SWT.PUSH);
         
      button.setText(">>");

                FormData data = "">new FormData ();
                data.right = new FormAttachment (100, -4);
                data.top = new FormAttachment (0, 4);
                button.setLayoutData (data);

                final Composite composite = new Composite(shell, SWT.BORDER);
                final FormData down = new FormData ();
                down.left = new FormAttachment (0, 4);
                down.right = new FormAttachment (100, -4);
                down.top = new FormAttachment (button, 4, SWT.BOTTOM);
                down.bottom = new FormAttachment (100, -4);
                final FormData up = new FormData ();
                up.left = new FormAttachment (0);
                up.right = new FormAttachment (0);
                up.top = new FormAttachment (0);
                up.bottom = new FormAttachment (0);
                composite.setLayoutData (up);

                button.addSelectionListener(new SelectionAdapter() {
                        public void widgetSelected(SelectionEvent e) {
                                if (composite.getLayoutData() == up) {
                                        composite.setLayoutData (down);
                                } else {
                                        composite.setLayoutData (up);
                                }
                                shell.layout(true, true);
                        }
                });

                shell.setSize (400, 300);
                shell.open ();

                while (!shell.isDisposed ()) {
                        if (!display.readAndDispatch ())
                                display.sleep ();
                }
                display.dispose ();
        }
}

Hi !

I'm newbi on this post list. I want to have informations about the
expandable group widget that was a investigation on the last SWT
milestone plan.

Me and my university school team are working on a final project and we
use SWT. We have a need for a widget like this. Does it will be done
eventually ? Maybe we should help to develop it or something like that
?

Please anyone can give me informations about that !

Thank you so much
